Well, KY, I often do change to rolls or to bread, but i also very often make one instead of two loaves - many of my favorite bread-pan bread recipes are for two loaves and we are only two at home now and so now i only make one.
I don't find freezing appealing :
1. because i have a small freezer, and a loaf of bread is too big - i need to save space for the weekly shopping, the meat, the coffee i can only find in a place on the other side of town, and other stuff.
2. I think if you freeze a whole loaf and defrost it all togther, you've lowered its keeping quality. (maybe i'm wrong here, but i wouldn't take soemthing out of the freezer and then use it as if it were fresh. so it would mean slicing it and wrapping a few slices with parchment paper between them and tigltly wrapping in plastic - not how i want to spend my day off.)
But i've made several bread recipes in half recipe quantities by volume,and done it very often, and they never had a problem. I swear.
I think that the fondness for weight and the reliance on proportions has made some pros jump to conclusions. I bet they tried to apply proportions, not measures to their halving of recipes. As for math, i never learned the tables, i count. But i do know logic. Maybe the recipes you tried to half either were badly halved ( as you say, not being good with numbers either...) or more likely, maybe you didn't try them as full recipes so you didn't know how they would have come if you'd done the whole one???
One of the reasons for my fondness for cup measures is that they are more easily halved. I don't need math, but just volume. I want half of 3/4 cup? I look at the cup, measure down half by eye and see where it comes! (If you want more precision, just put a piece of paper on the 3/4 measure, fold in half, and there you have it, fill to there! No need for those pesky division tables, or remembering fractions and all that). How to double 1-1/8? Fill to 1-1/8 twice! Just try that with 236.588 grams! Considering myself handicapped, i found a way to function.
The other thing is that if they have a recipe in cups that was originally in grams, they've certainly rounded out the measurements because i doubt very much that the original recipe calling for a cup of water was actually calling for 236.588 grams. Which tells you there is a certain leeway.
